Messier 13 – 2018-05-13

Messier 13

As a secondary target, I imaged the Hercules Cluster, M 13, NGC 6205, Mel 150 [globular cluster in Her]  5.8m ø17′ [wiki] [simbad] 400mm, 600mm, 750mm, 800mm, 1000mm, 1200mm, 1500mm . It came out somewhat unexpectedly well, considering M64. I acquired 8×180 sec and 7×90 sec, ISO 1600, with the usual setup, N 150/750, Baader MPCC Mark III, Canon 1100D mod, HEQ5.

 

The bright galaxy is NGC 6207 [galaxy in Her] 11.7m ø3′ [wiki] [simbad] [photo-planner] and the fainter yet still obvious is IC 4617 [galaxy in Her] [wiki] [simbad] [photo-planner]

Messier 64 – 2018-05-12

Messier 64

The Moon was no issue on 2018-05-12-13, since the solstice is very near and the astronomical dawn started earlier than the rise of the not yet new moon. The seeing was below average, and it was windy, but I managed to image the Black Eye Galaxy, Messier 64, gathering 15x240sec, 11x90sec with my usual equipment, N 150/750, Baader MPCC Mark III, Canon 1100D mod, HEQ5, at ISO 1600, the rest of the frames, almost half falling victim to the wind.

The object itself is fairly small for this equipment, measuring only 1/3 of the moon’s diameter, and the camera has a small resolution sensor – only 12MPs which though otherwise ok (large pixels gather more light, smaller guiding errors don’t really show up), leaves very little room for cropping.

M 64, NGC 4826 [galaxy in Com] Black eye galaxy, Feketeszem-galaxis 8.4m ø10′ [wiki] [simbad] 750mm, 800mm, 1000mm, 1200mm

The 37 Cluster – NGC 2169

NGC 2169, Col 83 [open cluster in Ori] 37 Cluster 5.9m ø6′ [wiki] [simbad] [photo-planner]  — from only two subs, because I wanted to see it with my own instruments.

Jól kalibrált monitoron mindegyik számnál elkülönülő árnyalat látszik. Ha mégsem látszanak, akkor a megjelenített képek színhiányosan rajzolódnak ki. A monitort valószínűleg kalibrálni kell.

You should see distinct shades for each number. If those shades are not clearly visible, the displayed pictures will lack accuracy. Your display most likely needs to be calibrated (brightness, gamma, contrast etc.).
